Abstract

The reaction of [Rh2(O2CMe)4] with PMe2Ph in Me3CCO2H gives the purple compound [Rh2(O2CCMe3)2{PMe2(C6H4)}2(Me3CCO2H)2]. Recrystallization from aqeuous methanol yields the corresponding bis-aquo adduct, which has been characterised crystallographically. That compound has a Rh-Rh bond length of 2.492(1) angstrom, and forms infinite hydrogen bonded chains in the solid state. Although compounds of this type with bridging triarylphosphine ligands have been characterised previously this is the first report of a fully characterised compound containing a tertiary phosphine ligand with both alkyl and aryl substituent groups.
